Her next solo album (release 22nd September 2017) is a seven-movement odyssey composed for analogue synthesizers and full, traditional 29-piece colliery brass band. The first album of its kind, Mary Casio: Journey to Cassiopeia explores one person's journey to outer space, by recounting the story of an unknown, elderly, pioneering, electronic musical stargazer and her lifelong dream to see Cassiopeia for herself. The journey continues Peel’s fascination with the brain and the explorative links between memory and music.
She released her 2016 solo album Awake But Always Dreaming her own label - My Own Pleasure. The album draws on personal experiences of her grandmother ‘awakening’ from dementia – Peel has described this album as ‘a dive into the rabbit hole of the brain’ earning her the accolade of ‘A latter day Delia Derbyshire” (The Observer) and 'No.1 Electronic Album of the Year' by Electronic Sound Magazine.
Peel first came to recognition with her modest yet mesmerizing, hand-punched ‘music box’ EP ‘Rebox’, featuring covers of ‘80s bands Cocteau Twins, Soft Cell, & New Order. She formed The Magnetic North, a highly acclaimed and expansive project with long term collaborator Gawain Erland Cooper (Erland & The Carnival) and Simon Tong (The Verve).
